    I did try some circles just for you. It kinda of skips. Maybe I was being too aggressive. It does not have turn find on it and has a pretty big prop so right now it's just set up to go fast straight. When I get 80, I'll putturn find on it for you and go carve some circles.

      Wow, 399. That is some some amps. Maybe a longer rudder would help with Chinewalk? I am not sure....
      Why are you bothering me? I want to see your boat!

        Why wait? Put some turn fins on that thing...you're going to be surprised when you do.

          This is one reason I have not painted the boat yet. I mounted the rudder up 1/4" higher than my first guess. I can move it lower and fill the holes in. One thing I have not done yet is eliminate slack in the steering. I had a chine walk type issue with the Daytona. At 69mph it was fine. If I broke 70mph and went through any small ripple other than glass smooth water, it would wag back and forth a few times and before I could chop the throttle, it would go flipping. I eliminated the slack and I picked up 10mph believe it or not. Little bit of slack will hurt more than you think at high speeds. Only slack I have is the rudder pin. I can move the bottom of the rudder around a bit. I'll address that by the weekend. Also I was thinking the strut being to far in the water making the prop too deep could be a factor, Keith says that's possible too. All the little things will add up. It's always a process but I don't mind it.

          Btw, my wifi is being suuuuper slow so the two videos still are not done.

            Pull that prop up and your amp will go way down ! Turn fins are night and day when it comes to the curves ! Awesome man !

              Trav, I think that you are going to have to play with props on this one. I am thinking 3 blades, detounged, something like a 645, maybe even something cut down. As well as getting the strut height just right. Just the right prop I'm sure will give magic numbers. It'll be a trial and error thing. But great stuff so far. It is a really nice looking boat. Waiting for the vids.

                    Dam ! That's moving ! Time to put some turn fins on and practice turning and at least 3 minutes of it ! lol

                      That's awesome.................I actually liked the 6s run better though, nice sound and looked so stable.

                        7s run was looking great right at the end.
                        Then you let off the throttle?

                            Thanks fellas! I'm wondering if the chine walking has something to do with having a 4s pack on one side and a 3s on the other. I'm going to make a weight stick to stick to the 3s battery to balance it out to see. I have a few ideas. I'll get past this hopefully. Here's another video, my very first 7s pass. I made several runs, didn't video every one.

I didn't want to say that because I don't like to count my chickens before they hatch....but I've had 75.4 of them hatch so far so I can say I'm pretty close. And this is only the second run. I'm going to be fighting some chime walk now so that's going to be a new learning curve on how to cut it down some. The water wasn't exactly smooth which is kind of needed for these speeds with this small of a hull. At least that's what I think anyway. I'm hoping that raising the strut will help some now. I'm uploading my data log at the moment so I'll check my amps again when that's done.


                              Looks like it's mid 200's with a peak of 399.
                              Hey Travis, it is looking good buddy. So at what point was the 399? And how long?

                              As far as your 7s imbalance, anything at that speed that isn't perfect can give grief. As you know. I think the weight is a good plan.

                                That spike was right when I nailed it for a split second. Average amps is about 250-260. Way too high for my liking. I knew that the prop is too deep but I didn't want to change anything else but calibrating the throttle. That's the only way I'd know how much it helped. Picked up 14mph just from that. Now it's time to start moving the strut and play with props.
